IiRivets zisisithambiso esiqhelekileyo esisetyenziswa ngokubanzi kwimveliso yoomatshini, i-aerospace, izithuthi, kunye namanye amashishini. Umsebenzi wabo ngokuyintloko ubandakanya amanyathelo amane aphambili: ukukhetha, unyango lwangaphambili, ukufakela, kunye nokuhlolwa komgangatho. Ukuthotyelwa okungqongqo kwiinkcukacha kubalulekile ukuqinisekisa amandla kunye nokuthembeka.
1. Ukhetho kunye noNyango lwangaphambili
Okokuqala, khetha uhlobo olufanelekileyo lwe-rivet (njengee-rivets eziqinileyo, ii-rivets ezingaboniyo, okanye ii-rivets ezingaboniyo) ngokusekelwe kubukhulu bezinto eziphathekayo, iimfuno zomthwalo kunye neemeko zokusingqongileyo. Idayamitha yerivet ngokuqhelekileyo iphindwe kathathu ukuya kane ubukhulu bephaneli ezidityanisiweyo, kwaye imathiriyeli kufuneka ihambelane ne-substrate (umzekelo, iirivethi zentsimbi zentsimbi, iirivethi zealuminiyam ze-aluminiyam). Ngaphambi kokufakela, coca iindawo ezidibeneyo ukuze ususe ioli kunye ne-oxide layers. Phawula iindawo zerivethi ngokuchanekileyo kwiiphaneli ukuqinisekisa ukuba isithuba siyahlangabezana neemfuno zoyilo.
2. Amanyathelo oFakelo
Iirivethi eziqinileyo zifakelwe kusetyenziswa umpu werivet okanye ihamile: Faka irivet ngomngxuma -ombiweyo ngaphambili. Khusela enye isiphelo se-shank nge-punch, kwaye usebenzise uxinzelelo kunye ne-rivet gun tip ukuya kwelinye icala, ukuguqula ibe yintloko. Iirivethi ezingaboniyo zisebenzisa i-rivet gun ukutsala i-mandrel, ibangela ukuba umkhono wandise kwaye ujikeleze ekupheleni kwe-shank, wenze isakhiwo sokutshixa. Gcina amandla amileyo ngexesha lokusebenza ukuphepha ukuphambuka kunye nokwakheka kwentloko engalinganiyo. Ii-rivets ezingaboniyo zifanelekile kwizicelo apho kuphela icala elinye lifikeleleka. Umsebenzi uyafana, kodwa izixhobo ezikhethekileyo zisetyenziselwa ukufikelela kwi-deformation evaliweyo.
3. Ukuhlolwa koMgangatho
Emva kokuphonononga, jonga intloko ukuze ubone imfezeko kunye nokuqhekeka-okungafezekiyo, kunye nokuzaliswa okupheleleyo komngxuma ngeshank. Qinisekisa ukhuseleko loqhagamshelwano ngokucofa, ukumamela, okanye uvavanyo lwetorque. Ukuba intloko iphezulu ngokungonelanga okanye i-shank yophukile, kwakhona{3}}i-riveting iyimfuneko.
I-riveting efanelekileyo ibalulekile kukhuseleko lwesakhiwo. Abaqhubi kufuneka baqeqeshwe kwaye basebenzise izixhobo ezifanelekileyo ukuthobela imigangatho yoshishino (njenge-GB / T 12618 okanye i-NASM).
